My baby jumps and wakes up the moment he's about to fall asleep; what causes this?

This situation that puzzles many parents is likely due to the "Moro reflex" (startle reflex). As the baby falls asleep, his muscles relax and his body's feeling of "letting go" can be interpreted as a falling signal — this triggers a sudden jumping movement that wakes the baby.
It's especially common in the first 4–5 months; it decreases naturally as the baby's nervous system matures. You can try a few small things: swaddling the baby more tightly (allowing hip movement but keeping arms close to the body) or gently pressing on his hand/chest as he falls asleep to reinforce the feeling of being "safe." If it continues intensely after 5–6 months, checking with your pediatrician would be appropriate.
